The invention fort-her provides 1 counterbalanced burner for centrally softening the lower of the bulb preliminary to opening the some for forming the cylinder after the bulb has otherwise attained the required diniensions.

The invention also embodies novel and peculiar operating means whereby the several parts may he mechanic lly controlied from a given point by the manipulation of switchlevers and valves, all as will more fully eppeur hereinafter.

For :i full description of the inVcntioneml the merits thereof and also to acquire a knowledge of the details of construction of the means for eii'ecting the result reference is to he had to the following description and drawings hereto attached. 7

While the essential and characteristic features of the invention are susceptible of-modilicntion, still the preferred embodiment of the invention is illustrated the accompanying drawings, in Which Figure 1 is c View in elevation of an appsfor working in accordance with invention, the heaters or furnaces, their hinge-mountings, and the lower portion of the column supporting the opernt' ports being in scct'on. Fig. 2 is side View a mechanism f working glass embodying the invention, ts being in section, thenpper he tor or "ii rnzice being open or thrown out of the way and the lower hen or or furnace hcing iilnstreted in position for softening the lower end of the bulb. 3 a View of the eppnrstus similar to 2, showing the position of the lower heater erfurnnce and the burner when at their lowestadjustment. Fig. 4 is a detail View of the heaters or furnaces and the mountings therefor, on a larger scale, the inner sections or lnilvcs of the furnaces being omitted. 5 is a top plen View of the parts shown in Fig. i. Fig. 6 a front yiew of the upper portion of the appsretns, on larger scele, the heaters or fur neces being open. 7, 8, and 9 are sectional detail views oi the three-way valve, showing (lili'eront positions.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the some reference characters.

The column for supporting the operating parts is indicated at 1 and is preferably hollow, so to be utilized as e motm-cylinder, in which a piston 2 is arranged to operate. The lower portion of the column 1 only serves as the motor-cylinder and may he an integral part of the column or coupled thereto in any diuni.

A sleeve 8 encircles the column 1 and rests upon the collar 5 and is movable with l the latter. A three-way valve 9 is interposed l in the length of the pipe 7 and controls the i admission of the motive orfiuid medium into i the motor cylinder at the lower end of the coli unm 1.. When the valve is turned to the pol sition substantially as shown in Fig. 7, the motive medium is admitted into said motor 1 cylinder and forces the piston 2 upward'therc- I in. \Vhen the valve is turned to the position substantially as shown in Fig. 8, the supply l of motive medium is cut ofl' from the motorcylindcr and the piston 2 is held at the required adjusted position. Upon turning the valve in the position approximately as shown I in Fig. 9 the fluid medium is permitted to esi cape from the motor-cylinder, thereby allowl ing the piston 2 and parts supported thereby l to descend. It will thus be understood that l by proper manipulation of the three-way valve the piston 2 may be elevated or lowered or held atany point within its range of movement.

The means for heating the bulb ot'glass during the expanding and elongating process em- I body a plurality of furnaces. the same being indicated at It) and ll. 'lhese heaters or t'nrl naces are of duplicate construction, each con- I sisting of complementalsections hinged iu'coaxial alinement with the column 1. The upi permosthcateror furnace it) is hinged directly l upon the column l and is held from vertical l movement, being supported upon the column l by means of a collar l2, secured to said coll unm. The lower heater is hinged upon the] sleeve s and is movable vertically therewith. An arm 12, is secured to the column at a point l between the upper and lower hinges ot' the I heater 1t) and supports a motorcylinder l-t. A corresponding arm 15 is secured to the sleeve Hata point between the upper and lower hinges of the heater ll and supports a 'niotorcylinder 16. The outer ends of the piston rods 17 of the respective motor-cylinders ls and lti are secured by links 18 to the sections 5 of the respective heaters or furnaces 1H and l 11. An arm 11) supports a trolley 20, which carries the weight of the upper piston-rod 17 l and nks loat their pointolconnection. The arm 15) is secured directly to the column I. A I flexible tube it conveys air or gas from the respective pipes 22 and 23 to the burner 24 ot' the upper heater or furnace It). This flexible tube is sitpported at a point between its ends by means of the trolley. 20. A flexible tube 25 connects the pipes 22and 23 with the burner 24' ot the lower heater or t'urnace ll and is l supported by means of a hanger JR forming a part ol the trolley 28, mounted to travel upon the arm T5 and supporting the pistonrods 17 and links 18 ot' the lower inotor-cylin- I der and furnace at their point of pivotal connection.

"alves AA are applied toopposite ends of l l the weight 40. By

the motor-cylinder 14 and control the admission of the motive medium thereto and the exhaustingot said motive medium when spent. 'lhese valves A A may be of any construction so long as they serve to regulate the inflow and the outflow of the motive medium. By preference the valves A A are of the type to be controlled electrically and are connected, by means of electric wires 29, to a switch-lever u of a switchl'ioard 30, the electric wires and switch connections being of any approved construction to admit of proper control of the ialves A A, so as to effect the desired result. Valves B B are connected to the motor-cylinder 16 for cooperation therewith in a manner similar to the valves A A and are connected, by means of electric wires 31, to the switch-lever b otthe switchboard 30. By manipulating the switch-lever m the sections of the heater or furnace It) may be opened or closed, and by operating the switch-lever 7) the sections of the heater or furnace 11 may likewise be opened or closed.

A burner 32, attached to an arm 33, is connected. by means of a rubber tube 31-, with air and gas pipes 35 and 36. The arm 33 is connected by slides 37, mounted upon a vertieal guide 38, said slides 37 consisting ot'sleeves connected by means of a plate 39. A weight 40, attached to one end of a rope or cable *1, serves as a counterbalance for the burner and attached parts. The rope or cable 41 passes over a sheave-pulley 42, suspended from a beam or other overhead support 43, and is connected at one end to the burnersupporting means and at its opposite end to mounting the burner 32 in the manner stated it may be raised or lowered and is held in the adjusted position by means of the counterbalance, as will be readily comprehended.

The blowpipe is indicated at H and is connected by a train of gearing 45 to a motor 46, so as to receive a reverse rotary movement. The motor 46 and connections 45 may be of any construction and arrangement so long as they serve to impart rotation to the blowpipe -14 in opposite directions.

In accordance with this invention a quantity of glass is taken up by means of the blowpipe 44, after which the blowpipe is rotated alternately in opposite directions, and at the same time air is forced through the blowpipe to expand the glass, so to as form the bulb 4:7. Simultaneously with the expansion of the bulb the latter is elongated by gravitative action. hen itis required to heat the bulb, the valve 9 is moved so as to admit motive medium into the motor-cylinder below the piston 2, thereby lifting the heater or furnace. 11 into a position adjacent to the heater or f-urmice 10. By turning the valve 9 into thoposition shown in Fig. 8 the heaiterlll held elevated. The furnaces 1t) and 11 are closed
